thanks for addressing & providing more on this painful disorder...CPS is called, known by other "names" , as Glen shared, most commonly Dx'd w/ some post stroke patients but is seen w/ other conditions,disorders , injuries, etc. affecting Brain, specifically the CENTRAL nervous system. (vs peripheral & other "systems")

I'm not as articulate nor knowlegeable as Glen (who is a Blessing --thanks so much !!)
I do suggest /encourage checking out some of these specific sites... on CPS
which does have similarities to PN, also RSD and other chronic pain disorders; and can occur with them & other conditions = PAIN.


www.centralpain.org is an excellent site w/ great links.

also,http://www.painonline.com
and
http://www.painonline.org/intro.htm (intro & more advanced articles)

http://health.groups.yahoo.com/group/CPS_ALLIANCE
is a wonderful caring & informative group; they're mission --besides support, is education and research.

There have been some threads & posts on CPS-Central Pain syndrome-- I believe in CHronic Pain forums?? and or elsewhere??

anyway... I have wondered about CPS since I 've heard descriptions, symptoms, causes and have had some dialogue w/ others who do have DX

issues have emerged for me RE: B12 --from recently received DR's report, .. as well as other problems .... too much for now & perhaps OT.....


wishing all the Best...
